Description

Technical Field

[0001] This utility model belongs to the technical field of automotive air conditioning parts, and in particular relates to a foldable muffler specifically for automotive air conditioning systems. Background Technology

[0002] As a crucial component of modern automobiles, the performance of automotive air conditioning systems directly impacts the comfort of drivers and passengers. However, the operation of these systems often generates noise, such as compressor noise, fan noise, and noise from airflow through ducts. This noise not only affects the driving experience but may also pose a potential threat to the hearing health of occupants. Therefore, automotive air conditioning system mufflers were developed to effectively reduce this noise and improve the quietness of the driving environment.

[0003] Currently, the mufflers commonly found in automotive air conditioning systems on the market mainly adopt expansion, resistive, or composite structures. Expansion mufflers increase the volume of the airflow channel, causing sound waves to be reflected and attenuated within the expansion chamber; resistive mufflers utilize porous sound-absorbing materials to absorb sound wave energy; and composite mufflers combine the advantages of expansion and resistive types, improving the noise reduction effect through a multi-stage noise reduction structure.

[0004] However, these traditional silencers still have some shortcomings in practical applications:

[0005] First, traditional mufflers often use a fixed muffler structure, which cannot adjust the muffler effect according to actual needs. When the car air conditioning system is running under different operating conditions, the frequency and intensity of the noise will change, and the fixed structure muffler is difficult to adapt to this change, resulting in unstable muffler effect. Second, when traditional mufflers are damaged or need cleaning, they often need to be replaced or disassembled as a whole, which is complicated and costly.

[0006] Therefore, it is essential to invent a foldable muffler specifically for automotive air conditioning systems. Utility Model Content

[0007] The purpose of this utility model is to provide a foldable muffler specifically for automotive air conditioning systems, thereby solving the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a foldable muffler specifically for automotive air conditioning systems, comprising a muffler end, a first connecting end, a second connecting end, a valve, a connecting pipe, a sound-absorbing plate, and a connecting frame. The air inlet end of the muffler end is fixed to the second connecting end via the connecting frame, and the exhaust end of the muffler end is fixed to the first connecting end via the connecting frame. Valves are fixed to the other ends of both the first and second connecting ends, and the other ends of the valves are connected to the corresponding structures of the automotive air conditioning system via connecting pipes. Sound-absorbing plates are fixed inside the muffler end, the first connecting end, and the second connecting end.

[0010] Furthermore, the sound-absorbing plate is arc-shaped; the outer side of the sound-absorbing plate is fixed to the inner wall of the corresponding silencing end, the first connecting end and the second connecting end, and a through hole is provided in the middle of the sound-absorbing plate. This arrangement can silence the gas passing through the silencer.

[0011] Furthermore, the connecting frame includes an adjusting sleeve, a sealing ring, and a fixing sleeve. The fixing sleeve is fixed to the outer side of the silencing end and the first connecting end, and the adjusting sleeve is rotatably installed inside the fixing sleeve through a sealed bearing. The adjusting sleeve is connected to the corresponding silencing end or the second connecting end through threaded engagement, and a sealing ring is provided between the adjusting sleeve and the corresponding silencing end or the second connecting end. The sealing ring is fixed to the corresponding silencing end or the second connecting end. This arrangement allows for adjustment of the spacing between the corresponding sound-absorbing panels, thereby adjusting the silencing effect.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The sound-absorbing plate of this utility model can change the internal cross-sectional diameter of the sound-absorbing end, the first connecting end and the second connecting end, thereby causing the sound waves to be reflected back towards the sound source through the sudden change of the cross-sectional diameter, thus achieving the sound-absorbing effect.

[0014] 2. This utility model, through the cooperation of the silencing end, the first connecting end, the second connecting end and the connecting frame, can adjust the spacing between the corresponding sound-absorbing plates, thereby adjusting the silencing effect. This design makes the muffler more flexible to adapt to the needs of different vehicle models and air conditioning systems, improving its practicality and adaptability.

[0015] 3. By setting valves, this utility model can cut off the airflow and prevent gas leakage when the silencer end, the first connection end and the second connection end are damaged or need cleaning. Then the damaged parts can be directly replaced or cleaned. Attached Figure Description
